ECB100
High Accuracy 3D Electronic Compass Board
Main Features
– Smallest Size: 16.5*16.5*6.5mm – 3D Angle (Heading, Pitch, Roll) Output – Heading Accuracy: 0.8° RMS (25°C, Tilt Angle<30°) – Pitch and Roll Accuracy: ±0.1° (25°C, Full Range) – Hard/Soft Magnetic Compensation, Tilt Compensation – Support User Calibration – Power Supply: 3.3±0.3VDC, Interface: LV-TTL – Widely Working Temperature: -40~+85°C

ECB100 electronic compass board is the smallest compass module that provides accurate heading and tilt readings, SkyMEMS’s advanced hard and soft iron correction algorithms allow for compensation of magnetic distortions inherent in the user’s system, resulting in reliable and consistent readings.
ECB100 integrates 3-axis magneto-inductive sensors, 3-axis MEMS accelerometer and central processing unit to calculate the heading data in real time and compensate the heading when it has inclination angle. ECB100 enjoys smallest size, high accuracy, low power consumption and low cost, which is very convenient to be integrated into different systems, it has been widely used in laser rangefinders, antenna positioning, buoy, unmanned systems and marine navigation fields, etc.

Remarks: · Arrow direction indicates positive angle direction · Heading angle that directs true north is 0° · Heading angle that directs true south is 180°
Installation
Though SkyMEMS E-Compass can compensate magnetic interference, please install and use the compass in the environment that has no or very little magnetic interference. And please keep the compass far away from iron, nickel, magnetic-iron, motors and other types of magnetic materials. Be sure that keeping strong magnetic materials (such as magnetic iron and motors) away from the compass, which will damage the compass’ accuracy, and the damage can’t be recovered. SkyMEMS E-Compass has done calibration in the factory, if using it in the environment where there is no or less magnetic interference, it can be used without the environment calibration. It is better to do the magnetic calibration in the actual application. The calibration procedure please refers to “User Manual of SkyMEMS E-Compass Second Calibration Software”. Remarks: during the calibration, the operator should not have mobile phone, keys, and other material that can generate the magnetic field.
